Workout at home-For flat stomach

Abdominal Crunches:

-Lie down on the floor on your back and bend your knees, placing your hands behind your head or across your chest.
-Pull your belly button towards your spine, and flatten your lower back against the floor.
-Slowly contract your abdominal, bringing your shoulder blades about one or two inches off the floor.
-Exhale as you come up and keep your neck straight, chin up.
-Hold at the top of the movement for a few seconds, breathing continuously.
-Slowly lower back down, but don't relax all the way.

Repeat for 15 to 20 repetitions with perfect form for each rep.

-To add variation, bring your knees in at the same time you lift your upper body off the floor (full body crunch)

Tips:

-To keep your neck in proper alignment, place your fist under your chin to keep your head from moving.
-Keep your back flat against the floor throughout the entire movement.
-If your back arches, prop your feet on a step or platform to make it easier.

Stay Fit :)
